Connector

Abstract

The present invention can increase reliability of a function for holding a force boosting function member at a fitting start position. This connector comprises: a slider (30) that is provided to a first housing (11), and that fits the first housing (11) together with a second housing (61) by being relatively displaced to a fitting completion position from a fitting start position with respect to the first housing (11); a holding part (42) that is formed at the slider (30) and that has an arm-shaped locking piece (43) extending in a cantilever manner in the same direction as the displacement direction when the slider (30) is relatively displaced from the fitting start position to the fitting completion position; a stopper (16) that is formed in the first housing (11) and that restricts the movement, to the fitting completion position, of the slider (30) at the fitting start position as a result of coming into abutment with an abutment section (45) which is an extending end of the arm-shaped locking piece (43) in the same direction as the extending direction of the arm-shaped locking piece (43); and a buckling restriction part (39) that is provided to the slider (30) and that restricts buckling of the arm-shaped locking piece (43).

1 . A connector comprising:
 a first housing;   a second housing configured to be fitted to the first housing;   a boosting function member provided in the first housing and configured to be displaced from a fitting start position to a fitting completion position relative to the first housing, thereby fitting the first housing and the second housing to each other;   a retaining portion formed in one member of the boosting function member and the first housing, the retaining portion including an arm-like locking piece extending in a cantilevered manner in a direction identical to a direction of displacement of the one member during the relative displacement of the boosting function member from the fitting start position to the fitting completion position;   a stopper formed in the other member of the boosting function member and the first housing and configured to restrict the boosting function member at the fitting start position from moving to the fitting completion position, by an abutment portion at an extended end portion of the arm-like locking piece abutting against the stopper in a direction identical to an extending direction of the arm-like locking piece; and   a buckling restriction portion provided in the boosting function member or the first housing and configured to restrict buckling of the arm-like locking piece.   
     
     
         2 . The connector according to  claim 1 ,
 wherein the buckling restriction portion is disposed on an opposite side of the abutment portion from the stopper.   
     
     
         3 . The connector according to  claim 2 ,
 wherein the retaining portion has a support portion in the form of a shaft extending in a direction perpendicular to the extending direction of the arm-like locking piece, the support portion connecting a base end portion of the arm-like locking piece and the one member, and   the arm-like locking piece is configured to tilt in a direction that increases or decreases areas of portions of the abutment portion and the stopper that face each other, while twisting and deforming the support portion.   
     
     
         4 . The connector according to  claim 3 ,
 wherein the support portion has a circular cross-sectional shape.   
     
     
         5 . The connector according to  claim 3 , comprising:
 a movement restriction surface that faces the support portion in a direction parallel to the extending direction of the arm-like locking piece.   
     
     
         6 . The connector according to  claim 3 ,
 wherein the retaining portion has a releasing extension portion extending from the base end portion of the arm-like locking piece in a direction opposite to the abutment portion,   the second housing has a retention release portion configured to interfere with the releasing extension portion as the second housing is fitted to the boosting function member, and   interference of the retention release portion with the releasing extension portion while the abutment portion is facing the stopper causes the retaining portion to tilt and the abutment portion to displace to a position where the abutment portion does not face the stopper.   
     
     
         7 . The connector according to  claim 6 ,
 wherein a separation distance from the support portion to a position of interference of the releasing extension portion with the retention release portion is smaller than a separation distance from the support portion to the abutment portion.   
     
     
         8 . The connector according to  claim 6 ,
 wherein the other member has a tilt restriction surface that faces the abutment portion from a side that is opposite to a direction of displacement of the abutment portion caused by interference between the retention release portion and the releasing extension portion.
